Abstract

Two new genera and three new species of cave-adapted ground beetles belonging to the tribe Trechini are established and described: Wulongius qilingergen. nov. and sp. nov. from limestone cave Qiankou Dong (Chongqing: Wulong), Qianotrechus congcongaesp. nov. from cave Shigao Dong (Chongqing: Nanchuan), and Qianlongius zhouigen. nov. and sp. nov. from cave Qianlong Dong (Guizhou: Songtao). Wulongius qilingersp. nov. is a small aphaenopsian beetle with a thin and elongated body, while Qianlongius zhouisp. nov. is a semi-aphaenopsian with a stout body. Both new genera are not closely related to any genus of Trechini occurring in the South China Karst, and so their systematic positions remain unclear.
